| Wetlands are ecosystems with specific features and functions which have been unfortunately damaged by recent pressures and limitations. Fast reduction of surface flows, water and wind erosion of soil, changes in the quality of water and soil resources, increasing exploitation of underground water, agricultural development, climate change, etc. have had the most effect on these ecosystems. So this study shows that in the last two decades, the level of groundwater has dramatically decreased as a result of human activities. Together with the decrease of water resources in Agh-Gol wetland area, land use has been also changed with a faster pace. Considering the studies on land use changes it can be stated that the amount of water in the area have had a decreasing rate so that it has been completely dried up these days. But hydrology studies warn us that there has been a thirty- five-meter reduction of water level in last years the main reason of which is planting products with the high water requirement. Also the minus water balance of this sub-area shows the unsuitable situation there. In general, this area has been faced with an instability which is caused by mismanagement. With a precise observation and control on water withdrawal from wells, using counters and plumbing illegal wells, banning planting close to thewetland, changing the planting patterns toward the productswith lesswater requirement and also optimizing watering,we can be hopeful that in future the situation will be improved andAgh-Golwetlandwill revive. | ||
